Hi,
MySQL Connector/Net 5.0.2 Beta has been released. MySQL Connector/Net is an
all-managed ADO.Net provider for MySQL. While this release is suitable for
any version of MySQL, it is strongly encouraged that this release not be
used on any production data.
It is now available in source and binary form from the Connector/Net
download pages at http://dev.mysql.com/downloads/connector/net/5.0.html and
mirror sites (note that not all mirror sites may be up to date at this point
of time - if you can't find this version on some mirror, please try again
later or choose another download site.)
Changes in this release (changelog):
Bugs fixed
----------
Bug #23268 System.FormatException when invoking procedure with ENUM input
parameter
Bug #23538 Exception thrown when GetSchemaTable is called and "fields" is
null.
Bug #23245 Connector Net 5.01 Beta Installer produces Antivirus Error
Message
Bug #23758 Unable to connect to any server - IPv6 related
Bug #22882 Registry key 'Global' access denied
Bug #18186 Problem with implementation of PreparedStatement
Other changes
-------------
Increased speed of MySqlParameterCollection.IndexOf(string) orders of
magnitude
(parameter name lookups are now strict on use of parameter marker)
Improved character set mappings
Turned MySqlPoolManager into a static class and added a static ctor
to avoid any race conditions related to initializing the hashtable.
Added 'Ignore Prepare' connection string option for disabling prepared
statements application-wide
Added Installer class to provide custom install type procedures such as
modifying
machine.config
A nicer exception is displayed if you have added a parameter without the
parameter marker.
Load Data Local InFile is working again
Installer now gives the user the choice of creating start menu items and
registering the provider in the GAC.
**********************************
** NEW CONNECTION STRING OPTION **
We have added a new connection string option named 'Ignore Prepare'. It is
a boolean option and its default value is true. This option, when true,
instructs the provider to ignore any calls to MySqlCommand.Prepare(). We
decided to do this because we have discovered some inconsistencies with
server side prepared statements which can lead to incorrect or damaging
results. If you are sure you want to use server-side prepared statements,
then you can add 'ignore prepare=false' to your connection string and it
will behave as before.
**********************************
Highlights of the 5.0.x Connector/Net releases:
* Support for ADO.Net 2.0 interfaces and subclasses
* Re-architected to improve speed and flexibility
--------------------------------------------------
The internals of the provider have been improved to allow column values to
be retrieved without boxing in many cases. Also, the internal changes have
enabled the future inclusion of embedded and client library support.
* Implemented Usage Advisor
---------------------------
The Usage Advisor first appeared in Connector/J. We have now implemented
that feature in Connector/Net. Enabling it causes the provider to check
both your queries and how you read the results and report to you if it
thinks you are using the provider in an inefficient manner. It checks such
things as using a query without an index, not reading all the columns or
rows from a resultset, etc.
* Implemented asynchronous query methods
----------------------------------------
The MySqlCommand object now supports asynchronous queries. This is
implemented using the BeginExecuteNonQuery and EndExecuteNonQuery methods.
BeginExecuteReader and EndExecuteReader are now included.
* Implemented stored procedure metadata caching
-----------------------------------------------
We now cache the metadata that is retrieved during stored procedure and
stored function execution. This cache data is used for subsequent
executions of that stored routine.
* Added PerfMon hooks
---------------------
This release includes PerfMon hooks to monitor stored procedure cache hits
and misses. We are looking at adding additional hooks in the first beta
release.
* Removed use of SharpZipLib library
------------------------------------
We have replaced use of the SharpZipLib library with the deflate support
available with .NET 2.0.
Support for embedded server and client library has been removed
------------------------------------------------------------------
For those of you that have seen my presentations on 5.0, we decided to
remove these features to help get 5.0 out the door more quickly. These
features will reappear in a later version of the product.
Thank you for checking out this release of Connector/Net.
